Abstract
A method for managing traffic of a plurality of packets in a plurality of packet flows transmitted using a time-slotted interface. The packet flows traverse a plurality of switches of a transport network according to an assigned path from a source node to a destination node. The method comprises determining (202) an end-to-end latency of a plurality of packets traversing a current switch in packet flows and assigning (204) priority to packets to the packets traversing the current switch, wherein a priority value of a packet depends on the determined end-to-end latency of said packets. The method further comprises allocating (206) a time slot in an output interface of the current switch to the packet having the highest priority value among the packets competing for said time slot.
